A connector for joining concrete structures such as double tee beams to one another. The connector includes a curved bolt that is formed with a shape memory alloy. Through utilization of the bolt, a joint can be post-tensioned following assembly through application of heat to the joint. Post-tensioning can be reapplied following loosening of the joint through application of heat. When considering a super elastic shape memory alloy, the bolt can be a smart bolt that can self-correct following deformation due to excessive load.

The joining device (100, 100′) comprises a first cover (1) and a second cover (2), each of which has a plurality of through holes (3) that match up with one another in position, for the ends of the rebars of the columns (200, 200A) to pass through. The covers (1,2) are joined together by means of, at least, two transverse webs (4) and several stiffener reinforcements (5,5A), which are arranged in perpendicular to the covers (1,2). The device further comprises connecting means (202, 203, 204, 205) between the ends of the rebars (201,201A) of the columns (200,200A).

A wind power plant tower segment is provided. The tower segment is designed as a jacket segment and comprises a reinforced concrete body, comprising two faces for attaching to faces of at least one further tower segment. In the region of each face, at least one connecting body is introduced in the reinforced concrete body and anchored therein for connecting to a connecting body of an adjoining tower segment. The connecting body comprises a fastening wall that is disposed substantially parallel to the respective face for absorbing a tensile load that is directed transversely to the face and transversely to the fastening wall. A wind power installation pylon having a plurality of such pylon segments, a wind power installation having a corresponding pylon, and a process for the production of a plurality of pylon segments is also provided.

The object of the invention is a column shoe for securing steel concrete columns to a base. The column shoe includes a bolt housing, which includes a baseplate provided with a bolt hole, and an upper structure which is connected to the baseplate and to which at least one attachment unit is connected for securing the column shoe and the steel concrete column together. The bolt housing is fabricated by casting such that the upper structure and the baseplate form a single-piece casting. A hole is formed in the bolt housing for the attachment unit. The upper structure of the bolt housing comprises a sleeve structure which is formed integrally with the upper structure and on which the hole for the attachment unit is formed, and the upper structure includes a wall structure by which the sleeve structure is connected with the baseplate.
摘要:
A form or a series of forms for forming the bridge diaphragm from concrete material includes one or more bottom walls having an inner surface thereof abutting a bottom surface of the diaphragm. There is at least a pair of side walls upstanding on the inner surface of the bottom wall or walls at a respective longitudinal edge thereof and has an inner surface thereof abutting a respective side surface of the diaphragm. The at least the pair of side walls define each of a generally open top and a generally hollow interior of the form. There is also means for securely attaching each end of the form or series of forms to one of a side surface of at least one of the pair of longitudinal members and an end of another form for forming the diaphragm from the concrete material. Bracing of upper edges is also provided.
摘要:
A device for joining a first building element to a second building element has a bridge element that is in contact with the first and second building elements to connect the first and second building elements when in a working position, and a first element secured to the first building element by being embedded therein. The first element cooperates with the bridge element. An elastic sleeve is arranged between the first element and the first building element. The elastic sleeve has at least one internal groove, thereby forming at least one cavity between the elastic sleeve and the first element.
